Stent-Assisted Coil Embolization of a Wide-Neck Aneurysm of a Persistent Primitive Hypoglossal Artery

Abstract

Persistent primitive hypoglossal artery (PPHA) represents the second most common carotid-vertebrobasilar anastomosis. The association of PPHA with intracranial aneurysms is not unusual. Treatment of aneurysms located on the PPHA itself is challenging due to the increased risk of ischemic complications secondary to the hypoglossal artery often being the sole contributor of flow to the posterior circulation. We report a case of a wide-neck aneurysm in a PPHA successfully treated using a stent-assisted coil embolization technique.

Unilateral Aplasia versus Bilateral Aplasia of the Vertebral Artery: A Review of Associated Abnormalities

“…Otherwise, associated aplasia of other vessels was related to the PCoA that was found bilaterally in 3/31 cases [ 20 , 33 , 41 ] and unilaterally in 1 out of 31 cases [ 23 ], as well as to the BA also in one case [ 43 ], and to some dural sinuses simultaneously with bilateral internal jugular veins in another case [ 30 ].…”

Coil embolization of a celiac artery aneurysm using the neck remodeling technique

“…If preservation of the native circulation is crucial for endovascular therapy of a visceral aneurysm, and the aneurysm has a wide neck and is long enough to insert a stent from the parent arterial orifi ce, coil embolization is possible through the mesh of the bare stent. 10 Although this is just one case report, our experience suggests that the coil packing method with the neck remodeling technique is a useful method for complete and safe coil packing of the visceral aneurysm, especially when the high risk of coil migration is anticipated owing to its wide neck and the native arterial circulation is essential for treating the aneurysm.…”

Superselective Coaxial Microballoon-Occluded Coil Embolization for Vascular Disorders: A Preliminary Report

“…The use of an adjunctive technique based on neck remodeling (19)(20)(21), stent-assisted methods (20)(21)(22), double-catheter methods (23), and double stent-assisted methods (24) enables dense coil packing to overcome the inherent difficulty of conserving the parent vessel during embolization of sessile aneurysms. In one patient with an STA aneurysm (patient 9; Table), the balloon catheter was used for neck remodeling, and tight packing was achieved.…”
